Which Virus Causes Genital Herpes

What Are The Causes Of Genital Herpes

Herpes (oral & genital) – causes, symptoms, diagnosis, treatment, pathology

Genital herpes is spread by skin-to-skin contact with someone who has the HSV virus, usually during genital or oral sex. It can also be spread through kissing, foreplay or non-penetrative sex.

  • HSV1 commonly causes cold sores on the lips or face.
  • HSV2 causes most genital herpes.

The HSV virus is most easily spread when there are blisters or sores, but it can still be passed even if a person has no current blisters or sores or other symptoms.

You cannot get genital herpes from things like hugging, swimming pools or toilet seats.

Treatment The First Time You Have Genital Herpes

You may be prescribed:

  • antiviral medicine to stop the symptoms getting worse you need to start taking this within 5 days of the symptoms appearing
  • cream for the pain

If you have had symptoms for more than 5 days before you go to a sexual health clinic, you can still get tested to find out the cause.

Genital Herpes Is Spread By Skin

The virus can be spread when someone with HSV has an episode or an outbreak characterised by having a sore, blister, ulcer or skin split . It can also be spread between episodes, when there is no sore, blister, ulcer or skin split present called asymptomatic viral shedding.

During viral shedding the virus is on the skin surface and can be spread through genital skin-to-skin contact, or from the mouth or face to genital skin during contact.

Myth #: A Blood Test Is The Best Way To Know If You Have Herpes

Blood tests are not always accurate and testing for herpes can be tricky. It can take two weeks to six months after being exposed to herpes before it is detected in the blood. To make matters more complicated, if you are low risk for herpes and asymptomatic, it increases your risk of a false positive result. Because of this, the Centers for Disease Control and Prevention recommends against routine testing for herpes unless you or your partner have symptoms. The most accurate test is when you are able to take a swab sample from a new herpes lesion, but often times the diagnosis is made by a clinician based on your history and report of symptoms.

Because the blood test can be expensive and inaccurate, it is not typically included in a sexually transmitted disease evaluation unless you ask your provider for it specifically.

In short, if you dont have symptoms, you dont necessarily need a blood test. If you do experience an outbreak, a skin swab not a blood test is your best bet for confirmation.

Different Ways Of Using Herpes Simplex Virus Type 1 For The Treatment Of Human Cancers

Broadly speaking, there are two types of HSV-1 vectors, both have been used in cancer treatment. Replication-defective vectors, in which transgene expression cassettes are inserted in a viral genome with one or a few essential viral genes deleted. Such vectors can effectively express transgene products, but are unable to replicate, except in cells that complement the deleted viral functions in trans. A special group of replication-defective HSV vectors are amplicons., , , In this approach, an expression cassette for the therapeutic transgene is placed in a plasmid that contains the viral packaging/cleavage signals and HSV-1 origin of replication. Defective HSV-like particles that contain concatemerized plasmid DNA is produced in eukaryotic cells that supply viral functions in trans. Conditionally replicating vectors, in which deletion of some nonessential viral genes results in viruses that preferentially infect, replicate in, and lyse tumor cells. Conditionally replicating vectors can also be modified to carry therapeutic transgenes to augment antitumor effects. This review focuses on the recent progress in using replication-defective and conditionally replicating HSV-1 vectors for the treatment of human cancers.

How Do You Get Herpes

The skin on your genitals, mouth, and eyes can be infected easily. Other areas of skin may get infected if theres a way for the herpes virus to get in, like through a cut, burn, rash, or other sores. You dont have to have sex to get herpes. Sometimes herpes can be passed in non-sexual ways, like if a parent with a cold sore gives you a peck on the lips. Most people with oral herpes got it when they were kids. A mother can pass genital herpes to a baby during vaginal childbirth, but thats pretty rare.

You can spread herpes to other parts of your body if you touch a herpes sore and then touch your mouth, genitals, or eyes without washing your hands first. You can also pass herpes to someone else this way.

Herpes is most contagious when sores are open and wet, because fluid from herpes blisters easily spreads the virus. But herpes can also shed and get passed to others when there are no sores and your skin looks totally normal.

Most people get herpes from someone who doesnt have any sores. It may live in your body for years without causing any symptoms, so its really hard to know for sure when and how you got it. Thats why so many people have herpes its a pretty sneaky infection.

Because the virus dies quickly outside the body, you cant get herpes from hugging, holding hands, coughing, sneezing, or sitting on toilet seats.

Prognosis Of Genital Herpes

Genital herpes can be treated and managed. Baill stresses that for most people who have healthy immune systems, the high-risk times for giving a sex partner genital herpes are during the first outbreak and during later outbreaks of sores.

Without such an outbreak, the viral load is usually not sufficient to infect a normal, healthy partner, she says. Antiviral medication can be effective at controlling the frequency and the severity of genital herpes outbreaks, Baill says.

For some people, though, even the times when no symptoms are present can be risky ones for transmission.

If you have genital herpes and your partner is taking biologic drugs for rheumatoid arthritis or MS or psoriasis, you may need to be extra careful, says Baill. It may take a lower viral load to infect people taking those medications.

In these situations, she says, you may want to take antiviral drugs in an ongoing way to keep your viral load low and protect your partner.

  • Herpes simplex virus , also known as genital herpes, is most likely to be spread when an infected person is having an outbreak, but it can also be transmitted without any symptoms being present.
  • Medications can help reduce your symptoms, speed up the healing of an outbreak and make you less contagious.
  • If you know you have genital herpes before becoming pregnant, your physician will monitor your condition throughout your pregnancy. If you have an active outbreak at the time of delivery, cesarean section may be recommended.

The Epstein Barr virus increases the risk of some cancer types. But, for most people that have the virus, it will not cause them any problems.

EBV is linked to Hodgkin lymphoma , Burkitt lymphoma and nasopharyngeal cancers.

How Does Genital Herpes Affect Pregnancy

Herpes simplex virus doesnt affect fertility or your ability to conceive. Pregnant women diagnosed with HSV-2 should start a daily antiviral at 36 weeks of pregnancy as prescribed, to prevent outbreaks during delivery. If you have an active infection at the time of childbirth, you can pass the herpes virus to your baby. Neonatal herpes puts a baby at risk for blindness, brain damage, skin infections and death. Your healthcare provider will perform a cesarean section to lower this risk.

Faqs About Cold Sores Answered

Most cases of genital herpes are caused by HSV-2. Since sexual contact is the major means by which genital herpes is transmitted, the illness does not usually arise before adolescence. When a child develops genital herpes, healthcare providers must consider the possibility of abuse. This is true whenever a person contracts a sexually transmitted disease prior to the teen years.

People at heightened risk for HSV-2 infection include those who have multiple sexual partners, women, people with low incomes, and those infected with human immunodeficiency virus . In fact, among people who tested positive for HIV, one study found that the prevalence of HSV-2 infections ranged from 70 to more than 90 percent.

  • A herpes sore on any part of the body
  • Saliva, if your partner has oral herpes, or genital fluids, if your partner has genital herpes
  • Skin around the mouth if your partner has an oral herpes infection, or the skin in the genital region of a partner who has genital herpes

You can catch genital herpes from a partner who has no visible sores, or from a partner who doesnt know that they have the infection. But a person is most infectious during their first outbreak of herpes, when they have sores, and during later outbreaks that produce sores.

Symptoms Of Oral Herpes

Oral herpes is most often caused by HSV-1, but can also be caused by HSV-2. It usually affects the lips and, in some primary attacks, the mucous membranes in the mouth. A herpes infection may occur on the cheeks or in the nose, but facial herpes is very uncommon.

Primary Oral Herpes Infection

If the primary oral infection causes symptoms, they can be very painful, particularly in children. Symptoms include:

  • Tingling, burning, or itching around the mouth are the first signs.
  • Red, fluid-filled blisters that may form on the lips, gums, mouth, and throat.
  • Blisters that break open and leak. As they heal, they turn yellow and crusty, eventually turning into pink skin. The sores last 10 to 14 days and can be very uncomfortable.
  • Blisters that may be preceded or accompanied by sore throat, fever, swollen glands, and painful swallowing.

Recurrent Oral Herpes Infection

A recurrent oral herpes infection is much milder than the primary outbreak. It usually manifests as a single sore, commonly called a cold sore or fever blister . The sore usually shows up on the outer edge of the lips and rarely affects the gums or throat.

Risk For Genital Herpes

According to the US Centers for Disease Control and Prevention , about 1 in 6 Americans ages 14 to 49 years have genital herpes. While HSV-2 remains the main cause of genital herpes, HSV-1 has significantly increased as a cause, most likely because of oral-genital sex. Except for people in monogamous relationships with uninfected partners, everyone who is sexually active is at risk for genital herpes.

Risk factors for genital herpes include:

  • History of an STD
  • First sexual intercourse at an early age
  • High number of sexual partners
  • Low socioeconomic status

Women are more susceptible to HSV-2 infection because herpes is more easily transmitted from men to women than from women to men. About 1 in 5 women, compared to 1 in 9 men, have genital herpes. African-American women are at particularly high risk.

People with compromised immune systems, such as those who have HIV, are at very high risk for genital herpes. These people are also at risk for more severe complications from herpes. Drugs that suppress the immune system, and organ transplantation, can also weaken the immune system and increase the risk for contracting genital herpes.

Can Herpes Be Prevented Or Avoided

The best way to prevent getting herpes is to not have sex with anyone who has the virus. It can be spread even when the person who has it isnt showing any symptoms. If your partner has herpes, there is no way of knowing for sure that you wont get it.

If you are infected, there is no time that is completely safe to have sex and not spread herpes. If you have herpes, you must tell your sex partner. You should avoid having sex if you have any sores. Herpes can spread from one person to another very easily when sores are present.

You should use condoms every time you have sex. They can help reduce the risk of spreading herpes. But its still possible to spread or get herpes if youre using a condom.

Got Ulcers Get Tested

A person with genital ulcers should see his or her doctor. Its important to confirm whether or not it is herpes. Genital herpes outbreaks are treated with antiviral medications. These medications can help to reduce the number of days of discomfort and have few side effects. They are most effective when taken early in an outbreak. Some people take these drugs daily to prevent outbreaks.

Once someone has had a test that confirms either type of genital herpes, future partners can have a blood test which tells them if they already have been exposed to the same strain of virus. If the person tests negative, the partner with the infection would be advised to take antiviral therapy daily, in order to help prevent infecting his or her partner. Although daily antiviral therapy decreases the chances of spreading the virus, there is no guarantee, so its best to have a frank conversation with a new sexual partner.
